Description

Technical Field

[0001] This utility model belongs to the field of nail remover technology, and in particular relates to a nail removal device for the production of environmentally friendly wooden doors. Background Technology

[0002] In the manufacturing process of wooden doors, fasteners such as metal nails and pneumatic nails are used extensively to fix structural components such as door frames and reinforcing ribs. If the remaining nails are not completely removed or properly handled during fine sanding and painting, the exposed or partially embedded nail heads will severely wear down the processing tools. The remaining nail heads will affect the surface treatment process, resulting in uneven paint or poor film adhesion, ultimately affecting the aesthetics and quality of the product.

[0003] Existing nail removal equipment requires workers to clamp the nail remover onto the nail cover, and then use the corner of the nail remover as a fulcrum to pry up and remove the nail. At this time, the corner presses on the wooden door, causing damage to the wooden door. Moreover, the nail is not pried up in a position perpendicular to the wooden door, which also causes damage to the wooden door. Utility Model Content

[0004] The technical problem this invention aims to solve is that when a nail remover is placed on a nail cover and the nail is pried up and removed using the corner of the nail remover as a fulcrum, the corner presses against the wooden door, causing damage to the door. Furthermore, the nail is not pried up perpendicular to the wooden door, resulting in further damage to the door.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a nail removal device for environmentally friendly wooden door production, including a triangular plate, a handle fixedly connected to the top of the triangular plate, and a nail-pulling plate provided at the bottom of the triangular plate, and further including...

[0006] The nail removal assembly is located at the bottom of the triangular plate and includes a hydraulic rod fixedly installed at the bottom of the triangular plate. The nail removal plate is fixedly connected to the free end of the hydraulic rod and is arranged in a horizontal C-shape.

[0007] Furthermore, the thickness of the inner wall at the notch of the nail-removing plate increases progressively, and the inner bottom of the nail-removing plate is provided with a circular slot, the diameter of which decreases progressively in a stepped manner.

[0008] Furthermore, the bottom of the triangular plate is fixedly connected to a bottom cylinder, which is arranged in a ring. The bottom of the bottom cylinder is open, and an electric push rod is fixedly installed on the inner top of the bottom cylinder. The output end of the electric push rod is fixedly connected to a piston, and a suction cup is provided at the lower end of the bottom cylinder.

[0009] Furthermore, a side plate is fixedly connected to the outer wall of the bottom cylinder, and a sliding column perpendicular to it is slidably connected to the side plate. A fixing ring is fixedly connected to the middle of the sliding column, and a spring is sleeved on the sliding column. The side plate and the fixing ring are fixedly connected to both ends of the sliding column, and a ball bearing is provided at the lower end of the sliding column.

[0010] Furthermore, both sides of the nail-pulling plate are provided with evenly distributed reinforcing ribs, which are arranged in a transverse U-shape.

[0011] Furthermore, a reinforcing plate is provided between the opposite sidewalls of the triangular plate, and a ring-shaped reinforcing frame is provided between the bottom of the triangular plate and the outer wall of the hydraulic rod.

[0012] The beneficial effects of this utility model after adopting the above structure are as follows:

[0013] (1) Place the entire device on the surface of the wooden door by holding the handle, and use the ball bearing to slide smoothly to achieve the smooth movement of the device, accurately position it to the target nail, insert the nail into the nail-pulling plate, and fix the upper end of the nail through the slot to ensure the stability of the nail during the nail-pulling process.

[0014] (2) Press down the triangular plate to drive the sliding column to slide vertically under the action of the spring, so that the suction cup is tightly attached to the surface of the wooden door. Control the electric push rod to retract and drive the piston to move upward, so that the suction cup generates negative pressure suction force, ensuring that the whole device is firmly fixed on the wooden door and avoiding displacement during operation.

[0015] (3) Control the hydraulic rod to retract and drive the nail puller plate to move smoothly upward in the vertical direction, so that the nail is pulled out in a state perpendicular to the wooden door. This avoids the pressure and damage to the wooden door caused by the traditional nail puller when it prys the nail at the corner as a fulcrum. At the same time, it prevents the nail from bending or enlarging the nail hole due to tilting force, effectively protecting the integrity of the wooden door surface structure.

[0023] like Figure 1-2 As shown, a nail removal device for producing environmentally friendly wooden doors includes a triangular plate 1, a handle 2 fixedly connected to the top of the triangular plate 1, a reinforcing plate 16 between the opposite side walls of the triangular plate 1, a nail-pulling plate 3 at the bottom of the triangular plate 1, and reinforcing ribs 15 evenly distributed on both sides of the nail-pulling plate 3, which are arranged in a transverse U-shape. It also includes a nail-removing assembly located at the bottom of the triangular plate 1.

[0024] like Figure 1-4 As shown, in order to prevent the nail from bending or enlarging the nail hole due to tilting force when removing the nail, the nail removal assembly includes a hydraulic rod 4 fixedly installed at the bottom of the triangular plate 1. A ring-shaped reinforcing frame 17 is provided between the bottom of the triangular plate 1 and the outer wall of the hydraulic rod 4 to increase the stability of the hydraulic rod 4. The nail removal plate 3 is fixedly connected to the free end of the hydraulic rod 4. The nail removal plate 3 is arranged in a transverse C-shape. The thickness of the inner wall at the notch of the nail removal plate 3 increases progressively. The inner bottom of the nail removal plate 3 is provided with a circular slot 5, and its diameter decreases progressively in a stepped manner.

[0025] like Figure 1-5 As shown, in order to provide stable support for the whole and prevent displacement during operation, the bottom of the triangular plate 1 is fixedly connected to the bottom cylinder 6, which is arranged in a ring. The bottom of the bottom cylinder 6 is open. An electric push rod 7 is fixedly installed on the top inner part of the bottom cylinder 6. A piston 8 is fixedly connected to the output end of the electric push rod 7. A suction cup 9 is provided at the lower end of the bottom cylinder 6.

[0026] like Figure 1-3As shown, in order to facilitate the movement of the whole without affecting the overall fixation, the outer wall of the bottom cylinder 6 is fixedly connected to a side plate 10. A sliding column 11 perpendicular to the side plate 10 is slidably connected to it. A fixing ring 12 is fixedly connected to the middle of the sliding column 11. A spring 13 is sleeved on the sliding column 11, and the side plate 10 and the fixing ring 12 are fixedly connected to its two ends. A ball bearing 14 is provided at the lower end of the sliding column 11. The smooth movement of the device on the wooden door is achieved by sliding the ball bearing 14. Applying pressure to the triangular plate 1 can make the sliding column 11 slide vertically under the action of the spring 13, so that the suction cup 9 is tightly attached to the surface of the wooden door.

[0027] In practical use, the reinforcing rib 15 can increase the overall strength of the nail puller plate 3. Hold the handle 2 and place the whole piece on the wooden door. Slide the whole piece to the nail removal point through the ball bearing 14, and the nail is stuck inside the nail puller plate 3 and the upper end of the nail is stuck in the corresponding slot 5. Then press down the triangular plate 1 to make the sliding column 11 slide vertically under the action of the spring 13. At this time, the suction cup 9 is pressed tightly against the top of the wooden door. Then control the corresponding electric push rod 7 to retract and make the piston 8 move upward. The whole piece is stably attached to the wooden door through the suction cup 9. Then control the hydraulic rod 4 to retract and make the nail puller plate 3 move vertically, so that the nail can be pulled out of the wooden door. This avoids the problem of pressing the wooden door with the corner of the nail puller as the fulcrum and the nail being lifted up in a state that is not perpendicular to the wooden door, which causes damage to the wooden door.
